ABSTRACT

Generation of expressive content is provided. An expressive synthesized speech system provides improved voice authoring user interfaces by which a user is enabled to efficiently author content for generating expressive output. An expressive synthesized speech system provides an expressive keyboard for enabling input of textual content and for selecting expressive operators, such as emoji objects or punctuation objects for applying predetermined prosody attributes or visual effects to the textual content. A voicesetting editor mode enables the user to author and adjust particular prosody attributes associated with the content for composing carefully-crafted synthetic speech. An active listening mode (ALM) is provided, which when selected, a set of ALM effect options are displayed, wherein each option is associated with a particular sound effect and/or visual effect. The user is enabled to rapidly respond with expressive vocal sound effects or visual effects while listening to others speak.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.15/347,653, filed Nov. 9, 2016, which is incorporated herewith byreference.

BACKGROUND

Alternative and augmentative communication (AAC) includes forms ofcommunication other than oral speech that are used to express thoughts,needs, wants, or ideas. An individual may rely on an AAC system as anaid to communicate when the individual is not able to communicateorally, for example, due to a speech disability. Some AAC systems areoperative to synthesize speech from the individual's input.

Conveying emotions, attitude, or tone through speech is oftentimesdependent on non-verbal communicative features, such as gestures andspeech prosody; however, current speech-generating AAC systems do notsupport conveyance of non-verbal information, and generally only provideusers with a text-to-speech engine and voice fonts that synthesize asingle flat tone of speech that is mostly devoid of emotion andexpressivity regardless of the input text that the AAC user is intendingto convey. For example, synthesized speech generated from an AAC user'sinput may sound robotic and lack volume and vocal inflection, whichmakes it difficult for the AAC user to effectively communicate in a waythat represents the user's internal voice. As can be appreciated, thiscan negatively impact AAC users' quality of life, specifically in theirinteractions with other individuals.

Oftentimes, to try to convey emotion or expressivity, an AAC user willtype and speak an additional explanatory phrase, such as “I am angry”before typing and speaking the phrase that the user intended to speakoriginally. As can be appreciated, this is inefficient and can present asignificant burden to AAC users, particularly when using gaze-based textentry, for which AAC users have a typical text entry rate of between10-20 words per minute.

SUMMARY

This summary is provided to introduce a selection of concepts in asimplified form that are further described below in the DetailedDescription section. This summary is not intended to identify keyfeatures or essential features of the claimed subject matter, nor is itintended as an aid in determining the scope of the claimed subjectmatter.

Aspects are directed to an automated system, method, and device forgenerating expressive content. By employing aspects of the presentdisclosure, an improved user experience is provided, where a user isenabled to efficiently and effectively compose expressive content, suchas prosody-enhanced speech, sound effects, or visual effects, usingvoicesetting editing.

An expressive synthesized speech system provides an expressive keyboardfor enabling the user to input textual content and for selectingexpressive operators, such as emoji objects or punctuation objects forapplying predetermined prosody attributes, sound effects, or visualeffects to the user's textual content. In some examples, the user mayselectively enter a voicesetting editor mode, where a voicesettingeditor UI is displayed for enabling the user to author or adjustparticular prosody attributes associated with the user's content. Insome examples, an active listening mode is provided. When the userselects to launch the active listening mode, a set of active listeningmode effect options are displayed, wherein each effect option isassociated with a particular sound effect and/or visual effect. Inconversations, the user is enabled to easily and rapidly respond withexpressive vocal sound effects or visual effects while listening toothers speak. Because the user does not have to type and speakadditional explanatory phrases to communicate emotions or expressivity,fewer processing resources are expended to provide input to theexpressive synthesized speech system, and the functionality of thecomputing device used to provide the expressive synthesized speechsystem is thereby expanded and improved.

Examples are implemented as a computer process, a computing system, oras an article of manufacture such as a device, computer program product,or computer readable media. According to an aspect, the computer programproduct is a computer storage media readable by a computer system andencoding a computer program of instructions for executing a computerprocess.

For example, substitutions, additions, ormodifications may be made to the elements illustrated in the drawings,and the methods described herein may be modified by substituting,reordering, or adding stages to the disclosed methods. Accordingly, thefollowing detailed description is not limiting, but instead, the properscope is defined by the appended claims. Examples may take the form of ahardware implementation, or an entirely software implementation, or animplementation combining software and hardware aspects. The followingdetailed description is, therefore, not to be taken in a limiting sense.

Aspects of the present disclosure are directed to a method, system, andcomputer storage media for providing intuitive synthesizedspeech-authoring user interface for generating expressive content. Whilemany of the examples described herein are directed to generatingexpressive content in an alternative and augmentative communication(AAC) system, as should be appreciated, aspects are equally applicablein a variety of alternative use cases and systems. For example inaddition to providing synthesized speech-authoring user interfaces tousers who are reliant on an AAC system to generate content, such asusers who have communication challenges stemming from severe motordisabilities, synthesized speech-authoring user interfaces may also beused for authoring or marking up documents that are to be rendered toaudio by automated or semi-automated means (e.g., marking up a printedition book to be rendered to an audio book, authoring a document to berendered by a screen reader program, authoring content in a web-basedcommunication service, and authoring content that is to be read aloud bylearning tool systems). With reference now to FIG. 1, a block diagram ofan example operating environment 100 illustrating aspects of an exampleexpressive synthesized speech system 108 for generating expressivecontent is shown. The expressive synthesized speech system 108 isoperative to provide improved synthesized speech-authoring userinterfaces via which a user 104 is enabled to efficiently andeffectively author content for generating expressive output, such asprosody-enhanced speech, sound effects, and visual effects. For example,prosody-enhanced speech includes speech that comprises variables oftiming, phrasing, emphasis, and intonation that speakers use to helpconvey aspects of meaning and to make speech lively.

The example operating environment 100 includes an electronic computingdevice 102. The computing device 102 illustrated in FIG. 1 isillustrated as a tablet computing device; however, as should beappreciated, the computing device 102 may be one of various types ofcomputing devices (e.g., a tablet computing device, a desktop computer,a mobile communication device, a laptop computer, a laptop/tablet hybridcomputing device, a large screen multi-touch display, a gaming device, asmart television, a wearable device, or other type of computing device)for executing applications for performing a variety of tasks. Thehardware of these computing devices is discussed in greater detail inregard to FIGS. 5, 6A, 6B, and 7.

According to aspects, the user 104 utilizes the computing device 102 forexecuting the expressive synthesized speech system 108, which inassociation with a text-to-speech engine (i.e., speech generation engine118), generates expressive synthesized speech from the user's input. Thecomputing device 102 includes or is in communication with the expressivesynthesized speech system 108. In one example, the computing device 102includes an expressive synthesized speech application programminginterface (API), operative to enable an application executing on thecomputing device to employ the systems and methods of the presentdisclosure via stored instructions.

In examples, the synthesized speech system 108 is operative to receiveinput (e.g., text input, mode selections, on-screen object selections,and prosody cue input) from a user-controlled input device 106 viavarious input methods, such as those relying on mice, keyboards, andremote controls, as well as Natural User Interface (NUI) methods, whichenable a user to interact with the computing device 102 in a “natural”manner, such as via technologies including touch sensitive displays,voice and speech recognition, intention and goal understanding, motiongesture detection using depth cameras, motion gesture detection usingaccelerometers/gyroscopes, facial recognition, 3D displays, head, eye,and gaze tracking, immersive augmented reality and virtual realitysystems, all of which provide a more natural interface, as well astechnologies for sensing brain activity using electric field sensingelectrodes (EEG and related methods). In specific examples, the user 104uses gaze-based input methods or head mouse input methods, which aretypically used by individuals who have communication challenges stemmingfrom paralysis or severe motor disabilities, such as people who haveadvanced amyotrophic lateral sclerosis (ALS).

Aspects of the expressive synthesized speech system 108 generate andprovide a graphical user interface (GUI) that allows the user 104 tointeract with functionality of the expressive synthesized speech system108. According to examples, the expressive synthesized speech system 108comprises an expressive keyboard UI engine 110, illustrative of asoftware module, system, or device operative to generate a GUI displayof an expressive keyboard. According to one aspect, the expressivekeyboard UI engine 110 provides a keyboard that extends an on-screenkeyboard, which is used to input text for speech synthesis, by providinga set of selectable icons or emoji objects that can be selectivelyinserted into the user's text. Each emoji object illustrates aparticular emotion (e.g., sad, calm, happy, funny, sarcastic, surprised,irritated, angry), and is associated with a predefined operation oroperations that can change the tone of voice of the user's text to aspecified emotional state (e.g., sad, calm, happy, funny, sarcastic,surprised, irritated, angry). For example, certain prosodic attributesare applied to the user's text based on the selected emoji object.According to one example, the expressive synthesized speech system 108is operative to apply a tone and emotion of output speech correspondingto a selected emoji object at a sentence level. According to an aspect,the expressive keyboard UI engine 110 is operative to intelligentlydisplay a set of emoji objects on the expressive keyboard, for example,based on linguistic properties of the user's textual input or based on arecognized emotional state of the user detected via a sensor (e.g.,biometric sensors, facial expression sensors, body posture sensors,gesture sensors). For example, the set of emoji objects may includeemoji objects associated with an emotion corresponding to the user'srecognized emotional state. In some examples, one or more emoji objectsare associated with a vocal sound effect (e.g., laughter, sarcasticscoff, sharp breath in, grunt, sigh, or a disgusted “ugh” sound). Whenthe user 104 selectively inserts an emoji object, a corresponding vocalsound effect is inserted at the beginning, end, or within the user'ssynthesized speech.

According to an aspect, the expressive keyboard UI engine 110 isoperative to receive the user's text input and selection of an emojiobject, and communicate the input and selection to a voicesetting engine114. The voicesetting engine 114 is illustrative of a software module,system, or device operative to receive user input, apply the predefinedoperation associated with the selected emoji object to apply speech orprosodic properties to the text input, and output a representation ofthe user's speech to a speech generation engine 118 for generatingaudible output 126 embodied as expressive synthesized speech. In someexamples, the voicesetting engine 114 comprises an index of emojiobjects and their corresponding operation(s), which includes prosodicattributes and/or vocal sound effects. The voice setting engine 114 isoperative to reference the index for applying the appropriate prosodicattributes and/or vocal sound effect to the user's text. According to anaspect, the voicesetting engine 114 specifies the text input andprosodic attributes and/or vocal sound effects via a markup language,such as Speech Synthesis Markup Language (SSML), which is output to aspeech generation engine 118. The audible output 126 is played on anaudio output device 128, which may be integrated with the user'scomputing device 102, or may be incorporated in another device utilizedby a communication partner 120.

In some examples, the expressive synthesized speech system 108 works inassociation with a visualization generation engine 116 for generatingexpressive visual output 122 for display on a visual output device 124from the user's input. For example, the predefined operation oroperations associated with each emoji object may include providing avisual feature, wherein, each emoji object may be associated with one ormore visual features (e.g., text, emoji, graphics, animations, videoclips). When the user 104 selectively inserts an emoji object into theuser's text input, the expressive keyboard UI engine 110 is operative tocommunicate the text input and the selected emoji object to thevoicesetting engine 114, wherein the voicesetting engine applies thepredefined operation associated with the selected emoji object to applyvisual features to the text input, and output a representation of thevisual features to a visualization generation engine 116 for generatingvisual output 122 for display on a visual output device 124. The visualoutput device 124 may be integrated with the user's computing device102, or may be incorporated in another device utilized by acommunication partner 120. In some examples, the visual output device124 and the audio output device 128 are incorporated in a single device.

According to another aspect, the expressive keyboard UI engine 110 isfurther operative to provide a plurality of punctuation objects (e.g., aperiod, comma, question mark, exclamation point), which when selectivelyinserted into the user's text, change prosodic attributes (e.g., silentspace, pitch, speed, emphasis) of surrounding words. In some examples, asettings menu is provided for enabling the user to customize theprosodic attributes or vocal sound effects associated with emoji objectsor to customize the prosodic attributes associated with punctuationobjects.

According to another aspect, the expressive keyboard UI engine 110 isfurther operative to provide a selectable active listening mode (ALM)for enabling the user 104 to select vocal sound effects and/or visualeffects for communicating information when a communication partner 120is speaking. For example, akin to using gestures, such as nodding, ornon-verbal vocalizations, such as laughing, in standard communication,the user 104 is enabled to use ALM effects to provide feedback to theuser's communication partner 120. According to examples, the expressivekeyboard UI engine 110 is operative to provide an ALM command, whichwhen selected, causes the expressive keyboard UI engine to display aplurality of selectable ALM effect options, wherein each ALM effectoption is associated with a particular sound effect and/or visualeffect. In some examples, the ALM effect options and associated sound orvisual effects are customizable by the user 104. For example, the user104 is enabled to select specific ALM effect options to display on thekeyboard. In one example, voice-banked recordings may be associated withsound effect options. For example, a voice-banked phrase or other soundeffect may be previously recorded by the user 104 or another individualand saved as a sound effect that can be selectively played or spoken bythe expressive synthesized speech system 108 during a conversation witha communication partner 120. In another example, an expression-bankedreaction may be previously recorded by the user 104 or anotherindividual and saved as a visual effect that can be selectivelydisplayed by the expressive synthesized speech system 108 during aconversation with a communication partner 120. Further, the user 104 maysave a static image or a video clip as a visual effect.

According to an aspect, the expressive keyboard UI engine 110 isoperative to receive the user's ALM effect option selection, andcommunicate the selection to the voicesetting engine 114 for outputtinga representation of the associated ALM effect to an audio output device128 and/or to a visual output device 124. The expressive keyboard UIengine 110 is operative to communicate the selected ALM effect option tothe voicesetting engine 114, wherein the voicesetting engine applies thepredefined operation associated with the selected ALM effect option toprovide audible features or visual features associated with the selectedALM effect option as output to a visualization generation engine 116 forgenerating visual output 122 for display on a visual output device 124or to an speech generation engine 118 for generating audible output 126for playback on an audio output device 128.

Aspects of the expressive keyboard UI engine 110 enable single-clickinput by the user 104 to quickly and easily specify the expressivenature of their speech and to rapidly respond with expressive vocalsound effects while listening to others speak. Aspects of the expressivekeyboard including the emoji objects, punctuation objects, and the ALMeffect options will be described in further detail below with referenceto FIGS. 2A-2P.

With reference still to FIG. 1, the expressive synthesized speech system108 further comprises a voicesetting editor 112 illustrative of asoftware module, system, or device operative to provide a GUI thatallows the user 104 to modify various prosodic properties associatedwith text input for asynchronously authoring expressivity of synthesizedspeech (e.g., outside of a face-to-face conversation). In some examples,the text input includes text composed via interaction with theexpressive keyboard. In other examples, the text input includes text inan existing text file which the user 104 is enabled to upload into theexpressive synthesized speech system 108. The voicesetting editor 112 isoperative to provide various controls for enabling the user 104 to editvarious properties of the output speech via coarse input methods, suchas via eye gaze or head mouse movement. According to aspects, the user104 is enabled to add detailed pacing, emotional content, or prosodiccontent to text before the text is rendered as speech. For example, thevoicesetting editor 112 provides controls for editing pause length,pitch, speed, or emphasis of specific text, and for inserting soundeffects and/or visual effects. According to examples, the user 104 mayutilize the UI provided by the voicesetting editor 112 when the userwants to have a higher degree of control over specifics of how theuser's text will be spoken when played by an audio output device 128.For example, the voicesetting text via the voicesetting editor 112typically entails additional time, and may be used by the user 104 in asituation where the user is preparing text to speak in advance (e.g.,before a medical appointment, before giving a public speech, whenpreparing stored phrases for repeated use). Aspects of the voicesettingeditor 112 will be described in further detail below with respect toFIGS. 3A-3G.

As described above, the expressive synthesized speech system 108 isoperative to provide intuitive synthesized speech-authoring userinterfaces via which the user 104 is enabled to efficiently andeffectively author content for generating expressive output, such asprosody-enhanced speech, sound effects, and visual effects. Examples ofsynthesized speech-authoring user interfaces provided by the expressivesynthesized speech system 108 are described below with reference toFIGS. 2A-3G. With reference now to FIG. 2A, an illustration of anexample UI displayed on a display 204 of a computing device 102 andgenerated by aspects of an expressive synthesized speech system 108 isshown. According to various aspects, the expressive keyboard UI engine110 is operative to generate an expressive synthesized speech system UI202 including an expressive keyboard 206 for enabling the user 104 toprovide text input 210, prosodic cue selections, and sound and/or visualeffect selections. Examples of the expressive keyboard 206 include analpha-numeric keyboard, which the user 104 is enabled to use to selectletters and numbers to author textual content 210 for speech synthesis.In some examples, the expressive keyboard 206 is a gaze-based on-screenkeyboard, wherein eye tracking is used to determine the user's gazeposition, which is utilized as a cursor. For example, to enter text 210,the user 104 may gaze on letters, numbers, or other displayed keys ofthe on-screen keyboard. In other examples, the expressive keyboard 206enables input via a head mouse input device 106, where the user's headmovements are translated into mouse pointer movement. In other examples,other input device 106 types are used for inputting textual content andproviding selections.

Examples of the expressive keyboard 206 further include a plurality ofselectable punctuation objects 208 a-n (collectively, 208), which theuser 104 is enabled to include with textual input 210 to specify theexpressive nature of the textual input. According to aspects, eachpunctuation object 208 has a predetermined operation associated with itthat specifies how particular prosodic attributes are to be applied tosurrounding text, thus changing the expressive nature of the speech thatwill be generated from the text.

For example, inclusion of a period, comma, or exclamation pointpunctuation object 208 may operate to insert a default oruser-customizable amount of silent space between pronouncing words orsentences, thus allowing the user 104 to set the cadence of his/herspeech. As another example, inclusion of a single question markpunctuation object 208 may operate to raise the pitch of a word locatedimmediately prior to the question mark, and inclusion of two questionmark punctuation objects may operate to raise the pitch of the two wordslocated immediately prior to the question marks to emphasize that thetextual content 210 is a question. As can be appreciated, this can beuseful in scenarios in which the user 104 asks a question that could beinterpreted as a statement if not for the question mark(s) (e.g., “Sheis meeting us there.” vs “She is meeting us there?”). As anotherexample, inclusion of an exclamation point punctuation object 208 mayoperate to increase the emotional tone, volume, or rate of speech of atleast a portion of the textual content 210, or to place emphasis on aspecific word of the textual content. As should be appreciated, thepunctuation objects 208 illustrated in the figures and described hereinare non-limiting examples. Other punctuation objects 208 and othercorresponding operations are possible and are within the scope of thepresent disclosure.

According to an aspect, the user 104 may enter textual content 210,select a punctuation object 208, and then select to play the text withthe punctuation object functionality applied. For example, the user 104may select a play command 212, which when selected, causes theexpressive keyboard UI engine 110 to pass the textual content 210 andthe selected punctuation object 208 to the voicesetting engine 114 forapplication of the prosodic attributes or prosodic propertiescorresponding to the selected punctuation object to the textual content.

As illustrated in FIG. 2B, the expressive keyboard 206 further includesa selectable ALM (active listening mode) command 214, which whenselected, causes the expressive synthesized speech system 108 to enteran active listening mode and the expressive keyboard UI engine 110 todisplay a plurality of selectable ALM effect options 216 a-n(collectively, 216), wherein each ALM effect option is associated with aparticular sound effect and/or visual effect that can be selectivelycommunicated to a communication partner 120. For example, selection ofan ALM effect option 216 enables the user 104 to provide rapidexpressive reactions when the communication partner 120 is speaking.With reference now to FIG. 2C, a plurality of example selectable ALMeffect options 216 are illustrated. As described above, the ALM effectoptions 216 provide the synthesized speech user 104 with single-clickaccess to a variety of sound effects and/or visual effects, which invarious examples, are customizable by the synthesized speech user.Although the example ALM effect options 216 illustrated in FIG. 2C aredisplayed as text, other display options are possible, such as images orsymbols.

According to an example and as illustrated in FIG. 2D, a user 104 and acommunication partner 120 may have a conversation. The first stepdepicts the communication partner 120 talking, and the user 104providing communication feedback to the communication partner 120 in theform of an “I'm listening” visual effect/output 122 that can be renderedon the communication partner's visual output device 124 in response to aselection of an ALM effect option 216. The second step depicts the user104 selecting another ALM effect option 216 for providing another visualeffect and/or sound effect to communicate with the communication partner120. For example, as the communication partner 120 is telling the user104 a funny story, the user selects a “laugh” ALM effect option 216.Accordingly, as depicted in the third step, a corresponding visualeffect/output 122 is displayed on the communication partner's visualoutput device 124, and a corresponding sound effect/output 126 is playedon the communication partner's audio output device 128. As illustrated,the user 104 is enabled to provide rapid expressive reactions during aconversation.

According to aspects, a variety of ALM effect options 216 may beprovided in the expressive keyboard 206, and a variety of correspondingaudio (sound) effects/output 126 and visual effects/output 122 may beprovided responsive to a selection of an ALM effect option. Variousexamples of visual effects/output 122 corresponding to various ALMeffect options 216 are illustrated in FIGS. 2E-2I. According to oneexample and with reference to FIG. 2E, an “I'm listening” ALM effectoption 126 may be provided, which when selected may provide a visualeffect/output 122 for display on a visual output device 124, such as thecommunication partner's visual output device. The visual effect may beembodied as one or more visual features representing the selected ALMeffect option 126, such as text 218 a saying “I'm listening,” ananimated dot object 218 b indicating that the user 104 is listening, anicon or clipart 218 c illustrating that the user is listening, anemoticon 218 d portraying listening, an animated avatar 218 e, or avideo clip 218 f that symbolizes listening.

According to another example and with reference to FIG. 2F, an “I'mtalking” ALM effect option 126 may be provided, which when selected mayprovide a visual effect/output 122 for display on a communicationpartner's visual output device 124. The visual effect may be embodied asone or more visual features representing the selected ALM effect option126, such as text 220 a saying “I'm talking,” an animated dot object 220b indicating that the user 104 is talking, an icon or clipart 220 cillustrating that the user is talking, an emoticon 220 d portrayingtalking, an animated avatar 220 e, or a video clip 220 f thatcharacterizes talking.

According to another example and with reference to FIG. 2G, an “I'mtyping” ALM effect option 126 may be provided, which when selected mayprovide a visual effect/output 122 for display on a communicationpartner's visual output device 124. The visual effect may be embodied asone or more visual features representing the selected ALM effect option126, such as text 220 a saying “I'm typing,” an animated dot object 220b indicating that the user 104 is typing, an icon or clipart 220 cillustrating that the user is typing, an emoticon 220 d portrayingtyping, an animated avatar 220 e, or a video clip 220 f thatcharacterizes typing or waiting for the user to finish typing.

According to another example and with reference to FIG. 2H, a “hold on”ALM effect option 126 may be provided, which when selected may provide avisual effect/output 122 for display on a communication partner's visualoutput device 124. The visual effect may be embodied as one or morevisual features representing the selected ALM effect option 126, such astext 220 a saying “hold on,” an animated dot object 220 b indicating towait or hold on, an icon or clipart 220 c illustrating for thecommunication partner 120 to wait, an emoticon 220 d portraying waitingor holding, an animated avatar 220 e, or a video clip 220 f thatcharacterizes waiting for the user 104.

According to another example and with reference to FIG. 2I, a “pardonme?” ALM effect option 126 may be provided, which when selected mayprovide a visual effect/output 122 for display on a communicationpartner's visual output device 124. The visual effect may be embodied asone or more visual features representing the selected ALM effect option126, such as text 220 a saying “pardon me?,” an animated dot object 220b indicating a question, an icon or clipart 220 c illustrating aquestion, an emoticon 220 d portraying a question, an animated avatar220 e, or a video clip 220 f that characterizes questioning.

As should be appreciated, the examples described above and illustratedin FIGS. 2E-2I are not meant to limiting. Other ALM effect options 126and other visual effects/output 122 are possible and are within thescope of the disclosure. For example, the visual output 122 can be in aspectrum from concrete to ambiguous, as well as the spectrum of low tohigh resolution. According to an aspect, visual output 122 may begenerated and provided automatically. For example, when the expressivecommunication partner's system 108 may detect that the user 104 istyping, and automatically provide a visual effect, such one or more ofthe “I'm typing” visual features or the “I'm talking” visual featuresdescribed above and illustrated in FIGS. 2F and 2G. Further, accordingto another aspect, the communication partner's visual output device 124could be embodied as a physical object that is configured to convey theother visual effects/output 122. For example, the visual output device124 may include an animatronic robot configured to move appendages,change positions and/or change facial expressions to reflect the visualoutput 122.

As described above and with reference now to FIG. 2J, the expressivekeyboard UI engine 110 is operative to provide a set of selectable iconsor emoji objects 228 a-n (collectively, 228) that can be selectivelyinserted into the user's text 210. According to an example, certainemoji objects 228 may be intelligently and selectively displayed, forexample, based on linguistic properties of the user's textual input orbased on recognized user affects detected via a sensor (e.g., biometricsensors, facial expression sensors, body posture sensors, gesturesensors). Each emoji object 228 illustrates a particular emotion (e.g.,sad, calm, happy, funny, sarcastic, surprised, irritated, angry), and isassociated with a predefined speech operation or operations that can adda sound effect (e.g., laughter, a sharp breath, a sarcastic scoff,grunt, sigh, a disgusted “ugh” sound, an angry “argh” sound), change thetone of voice of the user's text 210 to a specified emotional state(e.g., sad, calm, happy, funny, sarcastic, irritated, angry), or acombination of both. For example, specific predetermined prosodicattribute settings may be associated with each emoji object 228.

As described above, the voicesetting editor 112 is operative to providea GUI that allows the user 104 to modify various prosodic propertiesassociated with individual words within input text 210 for explicitlyauthoring expressivity of synthesized speech. With reference now to FIG.3A, the user 104 is enabled to select to use the voicesetting editor112, for example, via a selection of a voicesetting editor command 302.

In response and with reference now to FIG. 3B, the voicesetting editor112 is operative to display a voicesetting editor UI 304 for enablingthe user 104 to author specific prosodic properties of the textual input210. According to an aspect, the voicesetting editor 112 is operative toparse the input text 210 into three types of tokens 305: words 308,punctuation 310, and vocal sound effects 306 (e.g., derived fromselected emoji objects 228 in the input text 210). As illustrated inFIG. 3B, the tokens 305 are displayed in reading order. According to anaspect, padding 312 is provided between the tokens for allowingsufficiently large gaze targets for gaze-based input. In some examples,sound effect tokens 306 include a textual description of the vocal soundeffect they represent (e.g., “laugh” for laughter, “argh” for angryeffect). According to aspects, the voicesetting editor 112 allows forsetting prosodic properties 314 on individual tokens 305 or over rangesof tokens.

Selection of a single token, for example, by dwell-clicking on aspecific token 305, opens a token editing interface, such as the exampletoken editing interface 316 illustrated in FIG. 3C, for editing prosodicproperties 314 associated with a single token. The token editinginterface 316 includes the selected token 305 displayed in the center ofthe interface, wherein modifiable prosodic properties 314 are displayedin a radial menu surrounding the token. According to an aspect, a radialmenu design used for single token editing reduces the amount of distancethe user's eye must travel during gaze-based input to change properties314 of the token, thus enabling efficient user interaction andincreasing user interaction performance.

Aspects of the voicesetting editor UI 304 allow for selecting a range oftokens 305 for editing. In one example and as illustrated in FIG. 3B, arange selector 318 is provided, which when selected, allows the user 104to select a range of tokens 305. For example, after selecting the rangeselector 318, the user 104 may select the first token 305 in the desiredrange, followed by a selection of the last token in the desired range.Responsive to selecting a range of tokens 305, the voicesetting editor112 is operative to display a token editing interface, such as theexample token editing interface 320 illustrated in FIG. 3D, for editingprosodic properties 314 associated with a range 322 of tokens 305.

According to examples, in the token editing interface 316, 320, a set ofprosodic properties 314 are displayed that the user 104 is enabled toadjust. According to an aspect, only the properties 314 that can beadjusted for a selected token 305 are displayed. Some prosodicproperties 314 can be applied to all three types of token 305, forexample, emotional tone, rate of speech, volume, and pitch. Otherprosodic properties 314 are adjustable for particular token types. Forexample, word tokens 308 have an emphasis property 314 b that allows theuser 104 to specify which words should be emphasized. As anotherexample, punctuation tokens 310 have a pause property 314 that allowsthe user 104 to specify an amount of silent time to synthesize betweenthe pronunciations of words.

Upon selection of a prosodic property 314, the voicesetting editor 112provides functionalities for enabling the user 104 to adjust the valueof the property. According to an aspect, a set of predetermined valueranges are provided for prosodic properties 314. In an example and asillustrated in FIG. 3E, a meaningful label 324 is associated with eachvalue. For example, the emphasis property 314 b may have the labels 324and values: “normal” (a default value that the user 104 is enabled toconfigure), “strong” (80%), and “very strong” (100%). Value adjusters326, 328 are provided for enabling the user 104 to adjust the value ofthe prosodic property up or down respectively.

With reference to FIGS. 3F and 3G, prosodic property values aredisplayed in the voicesetting editor UI 304 using visual properties. Inone example, emotional tone 314 f, volume 314 d, and rate of speech 314e properties are displayed as lines over tokens 305. According to anexample, the labels 324 associated with the properties are displayed onor near the lines. According to another example, voice pitch 314 c isdisplayed using a corresponding baseline height 334 (e.g., the higherthe baseline height, the higher the pitch, the lower the baselineheight, the lower the pitch). According to another example, emphasis 314b is displayed using font boldness 336 (e.g., bolder font corresponds toheavier emphasis). According to another example, pause length 314 g isdisplayed using an ellipse 332, wherein the width of the ellipse 332corresponds to the pause length according to inter-word or punctuationtokens.

Having described an operating environment and various user interfacedisplay examples with respect to FIGS. 1-3G, FIGS. 4A and 4B are flowcharts showing general stages involved in example methods 400, 420 forgenerating expressive content.

At DECISION OPERATION 408, a determination is made as to whether tolaunch the voicesetting editor 112 for editing prosodic properties 214associated with the user's textual content 210. For example, thedetermination may be made based on whether the user 104 selects avoicesetting editor command 302. When a determination is made to launchthe voicesetting editor 112, the method 400 proceeds to OPERATION 410,where the voicesetting editor 112 parses the textual content 210 and anyselected punctuation objects 208 or emoji objects 228, and displays avoicesetting editor UI 304 for allowing the user 104 to adjust or refineprosodic properties 214 for crafting the rendering of the user's contentby a synthetic voice.

The method 400 proceeds to OPERATION 412, where the user 104 makes oneor more prosodic property 214 selections, and at OPERATION 414, theprosodic attributes, vocal sound effects, or visual effects associatedwith selected emoji object 228 and/or punctuation object 208 are appliedto the textual input 210.

At OPERATION 416, the combined textual input 210 and prosodicattributes, vocal sound effects, or visual effects are output to aspeech generation engine 118 for generating expressive audible output126 for playback on an audio output device 128 or to a visualizationgeneration engine 116 for generating expressive visual output 122 fordisplay on a visual output device 124. The method 400 ends at OPERATION418.

With reference now to FIG. 4B, the method 420 begins at start OPERATION422, and proceeds to OPERATION 424, where the expressive keyboard 206 isdisplayed in the expressive synthesized speech system UI 202.

The method 420 proceeds to OPERATION 426, where a selection to launchthe active listening mode (ALM) is received. For example, the user 110may select an ALM command 214 displayed on the expressive keyboard 206.

The method 420 proceeds to OPERATION 428, where responsive to the ALMcommand 214 selection, the expressive synthesized speech system 108enters an active listening mode and the expressive keyboard UI engine110 displays a plurality of selectable ALM effect options 216, whereineach ALM effect option 216 is associated with a particular sound effectand/or visual effect that can be selectively communicated to acommunication partner 120.

The method 420 proceeds to OPERATION 430, where a selection of an ALMeffect option 216 is received. At OPERATION 432, the expressivesynthesized speech system 108 identifies the vocal sound effect and/orvisual effect corresponding to the selected ALM effect option 216, andoutputs the corresponding vocal sound effect and/or visual effect to aspeech generation engine 118 or visualization generation engine 116 forgenerating audible output 126/visual output 122 for playback/display ona communication partner's 120 device 128/124. The method 420 ends atOPERATION 434.
